HTML Escape is the process of converting special characters in text (like <, >, &, ", ') into HTML entities (e.g., <, >, &) so they can be safely rendered in web pages without being interpreted as HTML code.
HTML Unescape is the reverse process—converting HTML entities back to their original characters, allowing the content to be displayed as intended.
Prevent Cross-Site Scripting (XSS): Escaping ensures that user input cannot be treated as executable HTML/JavaScript.
Protect Web Page Structure: Prevents malformed HTML caused by unintended tags or attributes.
Ensure Correct Display: Characters like < or & are displayed as text instead of being interpreted as part of the markup.
Support for HTML Data Interchange: Allows special characters to be safely stored and transported within HTML documents.
To Escape:
Use online tools, HTML libraries, or functions (e.g., html.escape() in Python or _.escape() in JavaScript).
Input your raw text, and the tool will return escaped HTML entities.
To Unescape:
Use the corresponding unescape function or tool.
Input escaped HTML, and it will return the original characters.
Escape when displaying user-generated content (e.g., comments, form inputs) in HTML to prevent injection attacks.
Unescape when parsing or displaying stored HTML content that was previously escaped for security or formatting.
When working with HTML in APIs, emails, or CMSs, to ensure consistent rendering and safety.
During data sanitization or rendering in web applications and frameworks.
